New Inlet Tube is ideal when setting new pool liners. The 4.0 flexible hose is connected to a header which reduces down to low profile rigid tube that is only 1.5 inches thick. Once inserted between the liner and the wall the inlet tube allows suction from both the bottom and the sides for maximum air flow and will not collapse under pressure. After the pool is filled, the inlet tube is easily removed without leaving any wrinkles in the liner.
